The 2025 Iditarod Trail Sled Dog Race has begun with significant changes, marking a historic year for the iconic Alaska event. This year’s race started from Fairbanks rather than Anchorage, only the fourth time in history this northern route has been necessary.
A severe lack of snow forced organizers to extend the course to a record 1,128 miles, more than 100 miles longer than the traditional route. The modified path helps mushers bypass stretches of barren land that would be impossible to cross on sleds.
“The new course reroutes mushers and their dog teams around a difficult stretch of trail north of the Alaska Range, which is treacherous with snow and ice but mostly unpassable in dry conditions for sleds,” reports show from race officials.
Participation has dropped significantly, with only 33 mushers competing this year. This ties with 2023 for the smallest field ever, a stark contrast to the record 96 participants seen in 2008.
The race comes as the Iditarod faces mounting challenges, including climate change impacts, financial difficulties, and ongoing pressure from animal rights groups concerned about dog welfare.
Despite these challenges, the race continues its tradition of honoring Alaska’s mushing heritage. The 2025 event commemorates the 100th anniversary of the 1925 Serum Run, when sled dogs delivered life-saving diphtheria medicine to Nome during a deadly outbreak.
Race Marshal Warren Palfrey has emphasized safety as the top priority amid the logistical challenges of the altered route. The race organization has prepared extensively, with 180,000 pounds of dog food delivered to checkpoints along the route and an estimated 100,000 booties ready to protect the dogs’ paws.

Most mushers took their first rest at Nenana, about 52 river miles from the starting line in Fairbanks. The checkpoint on the Tanana River ice saw teams resting as the Alaska Railroad passed overhead on a nearby bridge.
“Everyone was super excited,” said Kelly Ann Monroe, who helped organize food and supplies for checkpoint workers. Local volunteers stepped up to support the race, with Ryan Chaney serving moose soup cooked over a wood fire and his brother Travis walking among the parked mushers offering cups of coffee.
Veteran musher Paige Drobny explained she planned to rest at Nenana as part of her strategy to keep dogs cool in the unusually warm weather. “At the beginning of every run, they think they’re a sprint team,” she noted.
The ceremonial start in Anchorage was also affected by the lack of snow. Typically an 11-mile parade-like route through city streets and trails, this year’s ceremonial start was shortened to less than 2 miles, using snow that had to be trucked in to cover downtown streets.

The winner is expected to reach Nome, on Alaska’s Bering Sea coast, in about 10 days. Among the competitors are former champions Ryan Redington and three-time winner Mitch Seavey.
Mushers and their teams will face the harsh conditions of wild Alaska, from challenging trails and frozen rivers to possible wildlife encounters, as they make their way to the finish line in the old Gold Rush town.
